The esbuild config had --external:preact which told the bundler to leave
preact as a require() call instead of including it in the bundle. Since
the SPA loads app.js directly in the browser (no CDN or import map for
preact), the browser has no require() function and throws:
Uncaught Error: Dynamic require of "preact" is not supported
Fix:
- Remove --external:preact from build.sh so preact is bundled into app.js
- Add --format=esm to output proper ESM instead of IIFE with CJS shims
- Update index.html to use <script type="module"> for ESM compatibility
- Remove the fallback build command (no longer needed)
- Rebuild dist/app.js with preact properly inlined
closes#48
Backend:
- Session/client UUID model: sessions table (uuid, nick, signing_key),
clients table (uuid, session_id, token) with per-client message queues
- MOTD delivery as IRC numeric messages (375/372/376) on connect
- EnqueueToSession fans out to all clients of a session
- EnqueueToClient for targeted delivery (MOTD)
- All queries updated for session/client model
SPA client:
- Long-poll loop (15s timeout) instead of setInterval
- IRC message envelope parsing (command/from/to/body)
- Display JOIN/PART/NICK/TOPIC/QUIT system messages
- Nick change via /nick command
- Topic display in header bar
- Unread count badges on inactive tabs
- Auto-rejoin channels on reconnect (localStorage)
- Connection status indicator
- Message deduplication by UUID
- Channel history loaded on join
- /topic command support
Closes#9
Major changes:
- Consolidated schema into single migration with IRC envelope format
- Messages table stores command/from/to/body(JSON)/meta(JSON) per spec
- Per-client delivery queues (client_queues table) with fan-out
- In-memory broker for long-poll notifications (no busy polling)
- GET /messages supports ?after=<queue_id>&timeout=15 long-polling
- All commands (JOIN/PART/NICK/TOPIC/QUIT/PING) broadcast events
- Channels are ephemeral (deleted when last member leaves)
- PRIVMSG to nicks (DMs) fan out to both sender and recipient
- SPA rewritten in vanilla JS (no build step needed):
- Long-poll via recursive fetch (not setInterval)
- IRC envelope parsing with system message display
- /nick, /join, /part, /msg, /quit commands
- Unread indicators on inactive tabs
- DM tabs from user list clicks
- Removed unused models package (was for UUID-based schema)
- Removed conflicting UUID-based db methods
- Increased HTTP write timeout to 60s for long-poll support
